While I work on this, I might as well tackle some other issues.

Before I start work, some timings with a vanilla tree as of today.
The timing isn't terrible (within a factor of two with Intel 8.1),
but of course, I don't know Intel's quality of RNG.

$ cat random-single.f90
program main
  real, dimension(10**7) :: a
  call random_number(a)
end program main
$ gfortran random-single.f90
$ ./a.out && time ./a.out

real    0m0.765s
user    0m0.730s
sys     0m0.036s
$ ifort random-single.f90
$ ./a.out && time ./a.out

real    0m0.362s
user    0m0.313s
sys     0m0.049s

$ cat random-double.f90
program main
  real(kind=8), dimension(10**7) :: a
  call random_number(a)
end program main
$ gfortran random-double.f90
$ ./a.out && time ./a.out

real    0m0.886s
user    0m0.804s
sys     0m0.077s
$ ifort random-double.f90
$ ./a.out && time ./a.out

real    0m0.402s
user    0m0.328s
sys     0m0.074s
